K2 Think V2

K2 Think V2 is a 70-billion-parameter, fully sovereign, open-source AI reasoning model excelling in complex problem-solving across math, science, and code.

K2 Think V2, developed by the Institute of Foundation Models (IFM) at Mohamed bin Zayed University of Artificial Intelligence (MBZUAI), is a 70-billion-parameter, open-source general reasoning model. This model distinguishes itself through efficiency, openness, and sovereignty, challenging the notion that larger models are always superior. Built on the K2-V2 Instruct foundation model, K2 Think V2 demonstrates strong performance in mathematical reasoning, long-context consistency, and complex task execution, achieving leading results on benchmarks like AIME2025, HMMT, and GPQA-Diamond. It offers end-to-end transparency, providing access to weights, training data, code, and evaluation tooling, reinforcing the UAE's commitment to AI sovereignty.
